Using CentOS. I cannot connect remotely and I believe it is related to fact I can only connect locally if DISPLAY is set to :0.0. Something is misconfigured but I can't figure out what.
>xhost + access control disabled, clients can connect from any host >emacs -d :0.0 #works >emacs -d 127.0.0.1:0.0 Cannot connect to X server 127.0.0.1:0.0. >emacs -d localhost:0.0 emacs: Cannot connect to X server localhost:0.0.
